COME 1742 and Australian Standards Traffic Signs

Cos'è come 1742?
COME 1742 is called the Manual of Uniform Traffic Control Devices. It is the main guide for Australian standards traffic signs. This manual gives the rules for making and using traffic control devices in Australia. It makes sure that road signs, Segnali, and markings look the same everywhere. This helps make roads safer and easier for everyone to use.
COME 1742 is different from other standards. It fits Australian driving and local habits. The manual uses special shapes and colours for each sign. Warning signs are yellow diamonds with black symbols. Regulatory signs have red circles around speed limits. The AS 1744 font helps drivers read signs quickly. This is important when driving fast. The manual also uses metric units like kilometres per hour. This matches the rules on Australian roads.
The manual of uniform traffic control devices has some special features. It uses local words like ‘Give Way’ instead of ‘Yield.’ School zone signs often have flashing lights to warn drivers. Temporary warning signs are rectangles with yellow or orange backgrounds. These look different from British signs. The manual mixes ideas from the US and Europe. But it changes them for Australian roads, tempo atmosferico, and land. It uses more symbols than words. This helps international drivers understand the signs. A volte, words are added for extra help.
COME 1742 covers the most common road signs. These include regulatory, warning, guide, and temporary signs. It tells what colours, forme, and sizes each sign should have. The manual also connects to other parts of the australian standards traffic signs series. COME 1743 explains the materials and how to put up signs. AS/NZS 1906 talks about reflectivity for seeing signs at night. This system makes a strong legal base for traffic control devices in Australia.
Nota: Contractors and councils must work together to use AS 1742 in different places. They face problems meeting local needs. This is hard in areas with many cultures and special road conditions. Flexible and fair ways help ensure Australian standards of traffic signs work for all road users.
Why Uniform Traffic Signs Matter
Having the same Australian standards traffic signs is very important for safety and following the law. When all road signs follow the same rules, drivers know what to expect. This is true no matter where they go in Australia. It helps stop confusion and mistakes on the road.
The table below shows how uniform traffic control devices help safety and the law:
Evidence Aspect | Descrizione |
---|---|
National Standards | Strict rules for size, forma, posizionamento, and reflectivity help people see signs and follow the law. |
Safety Impact | Bigger, clear signs lower accident risks by up to 30%. They also help courts keep fines. |
Riflettività | Reflective signs lower night-time crashes by 6%. |
Legal Compliance | Signs that do not follow the rules may be illegal and fines may not count. |
Caso di studio | Bigger chevron signs helped drivers turn safely and lowered accidents. |
Environmental Adaptation | Bigger signs are used on fast or tricky roads so drivers can see them better. |
Manutenzione | Checking signs often keeps them easy to see and legal. |
Studies in Australia show that up to 80% of drivers slow down after seeing radar speed signs. Average speeds drop by 10% A 20%. In some places, deaths on the road dropped by as much as 79% after new signs and speed checks started. Luminoso, reflective signs have led to 25% fewer accidents than old signs. These facts show why standard traffic control devices are important for road safety.
Uniform Australian standards traffic signs also help with following the law. Signs that do not meet the rules may not count in court. This can mean fines are cancelled and drivers get confused. By using the manual of uniform traffic control devices, authorities make clear rules. These rules protect everyone on the road.
Australian standards traffic signs must work in many places. These include busy cities and quiet country roads. People must change their plans to fit local needs, tempo atmosferico, and land. They must also think about culture, especially in Aboriginal and Torres Strait Islander areas. Fair planning and talking to people helps make sure traffic control devices work well for everyone.
Mancia: Checking and fixing road signs often keeps them clear and easy to see. This helps keep roads safe and supports the law.
Structure of the AS 1742 Series
Overview of Parts 1–22
The AS 1742 series talks about many things for road signs. Each part has its own topic. COME 1742.1 gives the main rules for using road signs, Segnali, e segni. This part helps people pick the right sign for each place. COME 1742.2 is about regulatory signs like speed limits and no entry. COME 1742.3 is for temporary traffic management signs. These are used when roads are being fixed or built. COME 1742.4 outlines the use of warning signs to alert drivers to potential hazards ahead, while AS 1742.5 through AS 1742.10 address guide signs, route markers, and signage intended for cyclists and pedestrians. Parking controls are covered in detail under AS 1742.11. The later parts talk about school zones, railway crossings, and other special places.
The table below shows some important parts and what they do:
Part Number | Main Focus |
---|---|
COME 1742.1 | General principles |
COME 1742.2 | Regulatory signs |
COME 1742.3 | Temporary traffic management signs |
COME 1742.4 | Segnali di avvertimento |
COME 1742.11 | Parking controls |
New changes to AS 1742.1 have clearer rules for where to put signs. There are also new rules for using reflective materials. These changes help people see road signs better. Councils and workers now check signs more often. They use better materials to keep everyone safe.
Application in Urban, Rural, and Road Construction Zones
COME 1742.1 is used in many places. Nelle città, road signs help with busy traffic and show people where to go. Regulatory and warning signs keep drivers safe at busy crossings. In campagna, bigger signs warn about sharp turns or animals. Road construction zones use temporary traffic management signs from AS 1742.3. These signs tell drivers about changes and help keep workers safe.
Temporary traffic management signs are very important during road work. Workers put these signs before and after the work area. This helps drivers slow down and follow new paths. COME 1742.1 gives clear steps for where to put signs and how high they should be. Parking controls from AS 1742.11 help manage space in cities and near schools. Each part of AS 1742.1 makes sure road signs fit different places and needs.
Mancia: Councils should look at the newest AS 1742.1 changes before starting new work. This makes sure all road signs are legal and easy to see.
Practical Use of Traffic Signs

Permanent and Temporary Signage
Permanent road signs guide drivers every day. These road signs include speed limits, stop signs, and direction markers. Councils use as 1742.1 to choose the right size, colour, and shape for each sign. This helps drivers understand the message quickly. Permanent signs stay in one place for many years. They use strong materials to last in all weather.
Temporary traffic management signs help during special events or short-term changes. Workers use these signs when roads close for repairs or parades. The signs often have bright colours and clear symbols. As 1742.1 gives rules for these signs so drivers can see them easily. Temporary signs must be removed when the event ends. This keeps the road clear and safe.
Road Construction Zones
Road construction zones need special care. As 1742.1 and other parts of as 1742 set rules for these areas. Workers use warning signs to alert drivers about hazards ahead. These signs are orange diamonds. In aree ad alta velocità, workers place them 200 A 250 metres before the hazard. Nelle città, they use 50 A 100 metri. Regulatory signs show new speed limits. These signs stand close to where the rule starts.
Informational road signs help drivers find detours and know how long the work will last. Workers also use cones, barriere, and flashing lights. These tools make the area safer for everyone. The Road Traffic Code 2000 and safety laws support these rules. As 1742.1 explains how high to place each sign and which post to use. This makes sure drivers see the signs clearly.
Parking and School Zones
Parking areas and school zones have their own needs. As 1742.1 and as 1742.11 guide councils on how to control parking. Nelle città, parking signs show where drivers can stop and for how long. These signs use clear times and symbols. Councils check these signs often to keep them up to date.
School zones use special warning signs. These signs tell drivers to slow down when children are near. Some school signs have flashing lights during busy times. As 1742.1 gives the rules for these signs. This helps protect children and keeps traffic moving safely.
Nota: Councils and workers should always follow as 1742.1 for every type of road sign. This keeps roads safe and helps everyone understand the rules.
Related Australian Standards
COME 1743 and Sign Standards
COME 1743 works with AS 1742 to set rules for traffic signs. These sign standards say what materials and shapes to use. They also tell how to make the signs. Councils and contractors use AS 1743 to pick strong materials. Aluminium and galvanised steel last in tough weather. The sign standards also include:
- Size codes from A to D match sign size to road speed and place.
- Special shapes, like octagons for STOP and triangles for GIVE WAY, help drivers spot them fast.
- Rules for reflective sheeting make signs easy to see at night.
- Regular checks make sure signs stay strong and clear.
Local authorities check all signs before putting them up. Temporary signs must follow AS 1742.3 to keep everyone safe during road works.
AS/NZS 1906 e Riflettività
AS/NZS 1906 gives the rules for reflective materials on traffic signs. Retroreflectivity helps drivers see signs at night or in bad weather. It works by bouncing headlights back to the driver. The standard lists different classes of reflective sheeting. Each class has its own job:
Reflective Class | Descrizione | Use on STOP Signs |
---|---|---|
Classe 1 | High-intensity prismatic or glass bead | Mandatory for public roads |
Class 1W | Wide-angle prismatic | Used for extra brightness |
Classe 2 | Lower reflectivity | Not allowed for STOP signs |
STOP signs must use Class 1 or Class 1W sheeting. This makes them bright and easy to see. Stronger, brighter materials help drivers react quickly and lower accidents. Cleaning and checking signs often keeps them bright and safe.
Integration for Compliance
To follow the rules, people must use AS 1742, COME 1743, e AS/NZS 1906 insieme. COME 1742 sets rules for size, colour, and where to put signs. COME 1743 gives details for how high to mount signs. It says 1.5 metres in the country and 2.1 metres in cities. AS/NZS 1906 makes sure the right reflective class is used. When these rules are followed, signs are legal, chiaro, and safe. Councils must also check that trees or other things do not block signs. Da questa parte, roads stay safe and the law is followed.
Mancia: Always check the newest sign standards before putting up new signs. This helps keep everyone safe and follows the rules for a long time.
Compliance and Common Mistakes
Ensuring Sign Standards
Following Australian standards traffic signs keeps roads safe and legal. Councils and contractors use clear steps to check signs. They get size and reflectivity charts from suppliers before buying signs. Each sign must show its AS 1742 code and size label on the back. Workers make sure the sign has the right size and reflectivity for its job, like regulatory or warning signs.
They also look at the sign series code, size in millimetres, and how bright it is. Local council rules and the latest AS 1742 documents help with these checks. Some places need bigger or brighter signs. Suppliers must give all details and charts to prove the signs are correct. Before putting up signs, teams check them and show proof to local authorities. This makes sure signs follow the road traffic code 2000 and keep everyone safe.
Mancia: Councils should read state-specific supplements and technical notes. This helps them stay up to date with changes in the road traffic code 2000.
Avoiding Common Errors
Mistakes in putting up traffic signs can cause confusion and danger. Using designs from other countries can make problems. Workers should use approved templates and standard designs from AS 1742.3. This keeps signs clear and the same everywhere. Regular checks help find damage, sbiadimento, or wrong placement. Good reflective and weather-proof materials, like Diamond Grade sheeting, help people see signs and meet the rules.
Signs must be spaced and placed properly. They need to be easy to see and far enough from intersections. This gives drivers time to react. Trees or parked cars should not block signs. Teams must follow the latest road traffic code 2000 regole. They should not mix styles or use signs that are not approved. Checking and fixing signs often keeps them clear and legal.
The table below shows how updating old signs helps with safety and following the rules:
Aspetto | Before Update | After Update |
---|---|---|
Riflettività | Hard to see at night | Easy to see anytime, meets AS/NZS 1906.1 |
Chiarezza del messaggio | Too many words, confusing | Chiaro, semplice, and important information |
Durabilità | Damaged by bad weather | Forte, weather-resistant materials and design |
Design Consistency | Different fonts, colori, symbols | Same fonts, colori, and symbols on all signs |
Nota: Checking and fixing signs often helps councils and contractors avoid mistakes. This keeps signs following the road traffic code 2000.
